High Performance Trays

The latest developments in tray technology move beyond the system limits of normal trays. When other trays start to entrain liquid, the Shell ConSep tray starts to feel comfortable. The ConSep tray offers up to 80% higher capacity than conventional trays and up to 50% higher than any other high performance tray while maintaining high mass transfer efficiency

The Shell ConSep trays utilize the principle of de-entrainment by centrifugal force to exceed the gravitational limitation of jet flood.

Characteristics:

• ConSep tray combines
  Large bubbling area and liquid handling capacity of the contacting Shell HiFi trays (right side of picture)
  Centrifugal Separator (left side of picture) in a single stage: Con(tact) and Sep(arator)
• Highest capacity tray available on the market: above system limit
• Ideal for increasing existing plant capacity (revamps):
  Suitable mainly for 1-for-1 revamping of tower equipped with high performance trays
  Do not require any welding to the tower wall
  Gives up to 40% more capacity than any high performance tray
• Experience with refinery and natural-gas liquids applications
• Application at low tray spacing can provide lower reboiler and condenser duties
• Proven technology and excellent reliability based on:
  Actual operating experience
  Extensive research and development
  FRI proven

The FRI test of the ConSep tray has performed in a 1.22m diameter tower with i-C4/n-C4 system at 11 bar. The tray used a 2-pass design.
